Im not sure if its normal one of my banties layed an egg with a little blot of blood and shes been fine since. Im not really sure what you could do, I know the eggs do seem to get get bigger with time. Hope someone can answer your question.

Every once in a while I'll get an egg with a little blood on it like that. Last spring, I found two eggs on successive days with blood streaks, and the second one was a lot bloodier than the egg in your picture. I went around and checked chicken bums and discovered that our Hermione had an injury of some kind just inside her cloaca.

I encouraged her to go broody to give her insides a chance to heal up. Fortunately, she's of a breed of chicken that goes broody at the drop of a hat. After the broody period when she started laying again, she was fine and has been fine since.

Occasionally I will find a small amount of blood on an egg, although like ninbeast, not ever that much. If you don't know who laid it, I would agree to check all hen bottoms and make sure no one is injured. Having said that, I had no problems with mine, after the initial discovery. I did check every day though for about a week. Hope that helps.

It was Rose the sex link. I looked at her bottom & I could see where it had seeped a little blood. I checked it a few hours later & it looked good as new I will continue to check her for a while & make sure it isn't a problem.
